Modify the Putty Knife 



1 . If you don't order a modified putty knife (922-6761 ) from Apple Service, purchase a 
putty knife with a 1.5-inch (38 mm), flexible metal blade. 





Using sandpaper (150 grit), file down the end of the putty knife (on one side) until it's 
slightly beveled. Rub the edge of the putty knife back and forth for about 2 minutes on 
the sandpaper.

Thermal Pad 

The thermal pad is located on the bottom housing. A new thermal pad is included with the 
logic board and the bottom housing, and the pads can be ordered separately as a kit (part 
number 922-6749). 

Replace the pad when: 

• the logic board or the bottom housing is replaced 

• the pad is torn, withered, or damaged 

Important: Never use thermal paste in place of the thermal pad. You must replace the 
thermal pad with a new identical pad. 



Procedure 

1 . Remove the original pad from the bottom housing or the logic board using a black stick 
or other nonconductive nylon tool. 

2. Remove the protective backing on the new thermal pad. Note: Avoid unnecessary 
contact with either side of the thermal pad as dirt and body oils reduce the thermal 
pad's conductivity. 

3. Place the new thermal pad on the bottom housing (as shown). Make sure the thermal 
pad has even contact with the bottom housing. There should be no air pockets.

Memory Specifications and Upgrades 

Mac mini computers have a single memory slot. This slot accepts a standard PC2700 or 
PC3200 184-pin DIMM with the following specifications: 

• PC2700 or PC3200 Synchronous DRAM (SDRAM) 

• 2.5 volt 

• 8-byte 

• non-parity 

• 64-bit wide 

• 184-pin module 

• maximum of 16 memory devices on the DIMM 

• unbuffered — do not use registered or buffered SDRAM 

• maximum height of 50 mm 

Using PC3200 memory does not provide additional speed benefits. Although the Mac mini 
supports PC3200 DIMMs, the PC3200 RAM will operate at PC2700 (333 MHz) speeds. 

The Mac mini has a 256 MB base memory configuration, which can be expanded up to a 
maximum of 1 GB.The Mac mini can be configured to order (CTO) with 512 MB or 1 GB of 
SDRAM. Additional memory should be installed by an Apple Authorized Service Provider. 

Video memory 

The Mac mini has 32 MB DDR of soldered SDRAM dedicated for video. Video memory 
cannot be upgraded. 

LED status 

The Mac mini has a power light located on the front of the computer in the bottom right 
corner below the optical drive slot. The LED displays a steady light, no light, or pulses, 
depending on the computer's status. Here's what the Mac mini's LED is telling you.

Reset the PMU 



How to Reset the PMU 

The Power Management Unit (PMU) is an integrated circuit (computer chip) typically found 
on a computer's logic board. As its name implies, the PMU is responsible for managing all 
aspects of the computer's power. It controls hard disk spin down, sleep and wake, some 
charging aspects, and how any devices attached to the computer affect sleep. 

If the settings in the PMU become corrupted, it can result in operational anomalies such as 
your computer not turning on, not displaying video, or not waking from sleep, among other 
things. In these situations, you may need to reset your computer's PMU. 

Resetting the PMU will not resolve issues in which the computer stalls or is unresponsive. 
A PMU reset should only be used as a last resort in the case of a hardware failure or when 
the power management system is suspected. Resetting the PMU returns the computer 
hardware, including NVRAM, to default settings and forces the computer to shut down. 

Before you reset the PMU, try restarting the computer instead, which may resolve the 
issue. If the computer has stopped responding, try these steps, in order, until the computer 
responds: 

• Force Quit (Option-Command-Escape) 

• Restart (Control-Command-Power) 

• Force Shut Down (press the power button for 10 seconds) 

If none of the above steps resolved the situation, reset the PMU. 

Reset the PMU with the Top Housing On 

1 . Unplug all cables from the computer, including the power cord. 

2. Wait 10 seconds. 

3. Plug in the power cord while simultaneously pressing and holding the power button on 
the back of the computer. 

4. Let go of the power button. Your computer should start up. 

Important: This procedure also resets the computer's PRAM. Be sure to reset your 
computer's time, date, and other system parameter settings as necessary. 

If none of the above steps resolved the situation, reset the PMU. Follow the procedures on 
the next page. 

10 - Mac mini Troubleshooting Reset the PMU 



Reset the PMU with the Top Housing Off 

You can also reset the PMU by directly pressing the PMU reset switch located on the logic 
board. Follow these steps to access the PMU reset switch on the logic boar 

1 . Unplug all cables from the computer. 

2. Remove the top housing. 

3. If necessary, remove the internal frame to access the battery. 

4. Measure the voltage of the battery in the battery holder. The battery should measure 
2.6V to 3.0V. If the battery does not have minimum voltage, replace the battery. After 
replacing the battery, wait 1 seconds and then reset the PMU (refer to the next step). 
If the battery voltage is good, go on to the next step. 

5. Press the PMU switch on the logic board, located in the rear right corner of the 
machine. Be sure to press it just once. Because of the restricted space, you may need 
to use a black stick to press this switch. 

Warning: Do not press the PMU reset switch a second time because it could 
adversely affect the PMU chip.
